Holdings of the King County Archives include graphical materials which provide locations or construction details of infrastructure such as roads, bridges, wharves and ferry landings, mainline and logging railroads, and streetcar rights-of-way; hiking, pedestrian and equestrian trails; fire, sewer and water districts; electricity transmission lines, and sewer system maps. Maps and plans can be either generated by King County agencies or acquired by them (for example, from railway companies or from housing developers).

Please contact the Archives with questions, or to schedule a viewing appointment.
